check this which deletes special characters

REPORT ychatest.
 
DATA : v_char(25) VALUE 'A-B^34567-987',
       v_char1 LIKE fist-searchw.
 
v_char1 =  v_char.
 
CALL FUNCTION 'SF_SPECIALCHAR_DELETE'
  EXPORTING
    with_specialchar    = v_char1
  IMPORTING
    without_specialchar = v_char1.
 
v_char =  v_char1.
 
WRITE : v_char.

Hi chandrasekhar,

Thanks for your reply.

I checked that FM already.But it will not cover some characters like {} etc.

So, I want to check the string which doesnt contain alpha numeric and give them some msg.

thanks

Hai Sukumar,

Here is the logic.

DATA:

W_ALPHA_NUMERIC(36) TYPE C.

CONCATENATE SY-ABCDE '0123456789' INTO W_ALPHA_NUMERIC.

Suppose you want to check W_VAR wheteher it has other than ALPHA_NUMERIC .

IF W_VAR CO W_ALPHA_NUMERIC.

*"Do your task here

ELSE.

MESSAGE 'Contains Non ALPHA_NUMERIC Values' TYPE 'E'.

ENDIF.

Regdards,

Hi,

Please try this.

data: str type string.
data: valid_characters type string.
 
concatenate '0123456789' sy-abcde into valid_characters.
 
str = '123ABC'.
 
if str co valid_characters.
   write: / 'Characters are OK'.
else.
   write: / 'Characters are not OK'.
endif.

hi sukumar,

try this code:

data: str type char62 value 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789'.

if var1 CO str.

continue.

else.

print error message.

endif.

• var1 is ur variable to b checked.

• length of str may be 36 if case of alphabet is known beforehand.

plz reward points if helpful.

rgrds,
